Decolorization of Textile Effluent by Immobilized Aspergillus terreus

Engade K.B and Gupta S.G

The present investigation envelopes the uptake of dyes from textile ef fl uent by a fungal culture Aspergillus terreus immobilized in various matrices.

Results con fi rmed that the percent adsorption of dyes from textile ef fl uent (1:4) diluted, by Aspergillus terreus immobilized in Loofa sponge after 48 hours was 91.1% with 8 loofa pieces.

The percent adsorption of dyes from undiluted textile ef fl uent by 8 pieces of loofa sponge immobilized with A.terreus was 50.5% in 48 hours. When pH of diluted ef fl uent was adjusted to 7.0 percent adsorption of dyes by 8 pieces of loofa sponge immobilized with A.terreus was 98.7%. Percent uptake of dyes at pH 7 by coconut fi bre and groundnut shell matrix immobilized with A.terreus in 48 hrs was 31.2% and 55% respectively and at pH 10 it was 27.4% and 37.8%.
